Memory and CPU Usage Profiling
It probably advisable to keep a separate branch specifically set up for profiling. That branch can just forked off a local ddc-head branch using:
darcs branch ddc-head ddc-profiling
After changing directory into the ddc-profiling branch I create a custom config in that branch by doing:
echo "BUILDFLAVOUR = devel_prof" > make/config-override.deps
The compiler can now be built using the make command.
Once we have the profiling version of the compiler built is a matter of running it on something appropriate. I usually choose the test program in test/90-Programs/Rover and run it as:
make cleanWar bin/ddc +RTS -hc -p -K100M -RTS --make test/90-Programs/Rover/Main.ds
This generates a profile output file named ddc.hp which can be converted into a profile graph using:
hp2ps -c ddc.hp
to generate the Postscript file ddc.ps.
